The vertical lines are not default. But yes, everything can be 
easily configured. For example to use booktabs, you can use 
something like:

#+BEGIN_SRC emacs-lisp
 (defun orgtbl-to-latex-booktabs (table params)  
   "Convert the Orgtbl mode TABLE to LaTeX using booktabs 
   package."
   (let* ((alignment (mapconcat (lambda (x) (if x "r" "l"))
                                org-table-last-alignment ""))
          (params2
           (list
            :tstart (concat "\\begin{tabular}{" alignment 
            "}\n\\toprule")
            :tend "\\bottomrule\n\\end{tabular}"
            :lstart "" :lend " \\\\" :sep " & "
            :efmt "%s\\,(%s)" :hline "\\midrule")))
     (orgtbl-to-generic table (org-combine-plists params2 
     params))))

 (eval-after-load "org-table"
   '(progn
      (setq orgtbl-radio-table-templates
         (delete-if (lambda (x) (equal (car x) 'latex-mode))
                  orgtbl-radio-table-templates))

      (add-to-list 'orgtbl-radio-table-templates
                   '(latex-mode "% BEGIN RECEIVE ORGTBL %n\n% END 
                   RECEIVE ORGTBL %n\n\\begin{comment}\n#+ORGTBL: 
                   SEND %n orgtbl-to-latex-booktabs :splice nil 
                   :skip 0 :no-escape t\n| | 
                   |\n\\end{comment}\n"))))
#+END_SRC 


Then orgtbl-insert-radio-table, puts something like:

% BEGIN RECEIVE ORGTBL the-name-of-the-table
% END RECEIVE ORGTBL the-name-of-the-table
\begin{comment}
#+ORGTBL: SEND the-name-of-the-table orgtbl-to-latex-booktabs 
:splice nil :skip 0 :no-escape t
| | |
\end{comment}


and a table like:

| A | B |
|---+---|
| a | b |
| 1 | 2 |

gets translated to:

\begin{tabular}{ll}
\toprule
A & B \\
\midrule
a & b \\
1 & 2 \\
\bottomrule
\end{tabular}
